Abstract: Disclosed herein is a surgical instrument configured for attachment to a surgical device. The surgical instrument includes a distal region having a curved internal surface configured to mate with a curved external surface of the surgical device, a rotational locking feature that limits rotational movement of the instrument with respect to the surgical device, and an axial locking feature that limits axial movement of the blade with respect to the surgical device. Methods of using the surgical instruments include sliding the axial locking feature past a corresponding axial locking feature on the surgical device, locking the axial locking feature to the corresponding axial locking feature on the surgical device (thereby limiting axial movement of the elongated blade with respect to the surgical device), adjusting the position of the surgical device using the surgical instrument, and disengaging the axial locking feature (for example, by using a disengagement instrument).

Abstract: An example expandable interbody device can include a structural body having an upper endplate and a lower endplate, where the endplates are shaped to nest tightly in a closed position. The device can include at least one wedge block and at least one linkage block arranged between the upper and lower endplates of the structural body. The device can include a drive screw threaded through the at least one wedge block and the at least one linkage block. The drive screw can be configured to rotate and drive the at least one wedge block to expand the upper and lower endplates of the structural body from the closed position to an intermediate position. Additionally, the drive screw can be further configured to rotate and drive the at least one linkage block to expand the upper and lower endplates of the structural body from the intermediate position to an open position.

An example interbody fusion device can include a plurality of vertebral endplates, and a body extending between the vertebral endplates. The body and the vertebral endplates can define an internal cavity. Additionally, each of the vertebral endplates can include a lattice structure and a frame surrounding the lattice structure, where the lattice structure being configured to distribute load. Each of the vertebral endplates can also include a plurality of micro-apertures having an average size between about 2 to about IO micrometers (?m), and a plurality of macro-apertures having an average size between about 300 to about 800 micrometers (?m).

Abstract: An expandable interbody device used as a prosthesis during spinal surgery. The expandable interbody device is configured to be inserted into the space between spinal disks to provide stability. The expandable interbody device includes a drive block, a linkage block, a drive screw, a first endplate, a second endplate, and at least two linkages. Rotation of the drive screw causes movement of the linkage block relative to the drive block and/or movement of the first endplate relative to the second endplate.

Abstract: Various implementations include an anterior cervical fixation plate for fixating portions of a cervical spine to facilitate bone fusion. The plate includes a first portion, a second portion, and a bridge. A first surface of the first portion and a first surface of the second portion each define two fastener openings extending from the first surface of the first portion to a second surface of the first portion. The first side and the second side of the centrally located bridge each extend from the second side of the first portion to the first side of the second portion. The second side of the first portion, the first side of the second portion, and the first side of the bridge define a first window. The second side of the first portion, the first side of the second portion, and the second side of the bridge define a second window.

Abstract: The bone anchor disclosed herein includes a tulip housing with a distal radially expandable portion, a threaded shank having a proximal ball head, a pressure cap, and a retaining ring that limits radial expansion of the distal radially expandable portion. During assembly, the pressure cap and the proximal ball head through the distal end of the radially expandable portion. The retaining ring is positioned around the distal radially expandable portion of the tulip housing to prevent distal movement of the pressure cap and the proximal ball head. The bone anchors disclosed herein are configured to be inserted without using tapping steps.
